[quote name='redstriper' timestamp='1406149513' post='2508883'] I was just looking for a rough idea of what the difference would likely be [/quote] measure the internal dimensions to get the volume and then plug all the info into WinISD to see what you get. With a new baffle and prosily new/modified ports it'll be a fair bit of work. Out of interest what are Flyte cabs made of to be so light?

[quote name='molan' timestamp='1406109053' post='2508332'] Have you seen this new Ampeg combo? [url="http://www.ampeg.com/products/bassamp/ba-210/#"]http://www.ampeg.com...assamp/ba-210/#[/url] It's designed to work with a very shallow tilt so it can be a standalone floor monitor - even looks like a PA style monitor when tilted with the amp controls down the side If you click the left or right wedge images you can see what I mean No idea on price yet but I am reliably informed that they are on their way across the Atlantic right now. . . [/quote] so... I don't think I would have ever considered that.... but... I may go find one to try when they come out.

[quote name='Chienmortbb' timestamp='1406117220' post='2508451'] To the three musketeers, My comments were not meant as a criticism just advice. I hope I did not upset anyone. I have found it a good idea to keep an open mind when it comes to design and i am learning a lot from what you guys are doing. Much of what I have learnt is from guys like Bill, Alex and Duke, and much of that seemed counterintuitive at the time. Bill on particular continues to push the boundaries on enclosure design. Keep up the good work. [/quote] well you just named it - 3 musketeers 112

[quote name='molan' timestamp='1406066017' post='2508090'] My PA guy says no In his opinion the core sound of a PA cab won't sound that nice with a bass running straight into it. He said you could use a sub cab to get some of the core fundamentals but the decent ones start to get pretty expensive, at which point you might as well buy a bass specific combo. He's been selling PA gear professionally for many years and also works with a couple of quality bass amplification brands as well. I would definitely trust his judgement on stuff. I think his summary was that if it worked really well to buy a powered PA cab as a bass monitor then loads of people would be doing it [/quote] fair enough - plan B then - or plan C......

[quote name='redstriper' timestamp='1406038450' post='2507746'] My requirement is for a lightweight cab suitable for dub reggae, so I do not need much treble or upper midrange. I currently use a small cab loaded with an Eminence 3015LF, which sounds good but it doesn't go as low as the new ACME 15" cab. It would sound better in a larger box, but I don't want to do that. Stevie suggested replacing the driver with a [color=#282828][font=helvetica, arial, sans-serif]3012LF, which would be better suited to the smaller box dimensions and sound deeper than the 3015LF.[/font][/color] [color=#282828][font=helvetica, arial, sans-serif]Would anyone else here care to comment on this idea, before I take the plunge?[/font][/color] [color=#282828][font=helvetica, arial, sans-serif]Specifically, what differences in tone and volume should I expect and is it a worthwhile modification, considering the work and cost?[/font][/color] [color=#282828][font=helvetica, arial, sans-serif]Apologies for the derailment.[/font][/color] [/quote] ACME 15"? typo I would think? Question - and not being fecicious - why not buy an ACME?

[quote name='molan' timestamp='1406025916' post='2507555'] I have actually used a pair of PA speakers to gig with once and they sounded greatp. To be fair they were Trace Elliot cabs (from the short period when Trace went into PA) and each one had a 15" and a 10" mounted concentrically so there was quite a lot air moving Are you planning on using a PA cab for front of house or just as a stage monitor with the main PA running FoH? We have a local PA guru who also knows a lot about bass gear so I've asked his opinion for you [/quote] most gigs I've ever played have been via the pa, and one of the places I play we all have our own in ears so while a nice preamp helps I'm not sure I need to spend loads on a poweramp/head and cab. Strikes me a powered pa speaker with a response -3dB at 40-50hz or so will have a good enough low end response , have dsp built in and be designed to be flatter through the freq range and be able to use for other things other than bass

[quote name='Bassmonkey' timestamp='1405983644' post='2507324'] Rock Factory in Castleford has a lot of used stuff. Worth a look . Andy [/quote] [quote name='molan' timestamp='1405984149' post='2507326'] There's often a lot on eBay. Biggest problem with so much used PA gear is that it's often trashed by the time it's sold. Not as many sound engineers with major PA GAS compared to bass players - they jus use stuff until it breaks [/quote] thanks guys! Yeah I've realised that Barrie! I'm half tempted to replace most my current rig with a active PA speaker. Smaller, lighter, DSP equipped and compared to the cost of new bass stuff not stupid priced. (btw as someone who works in a specialist bass shop and has had a LOT of gear... any thoughts on my idea/plan)

[quote name='Bill Fitzmaurice' timestamp='1405979350' post='2507282'] Changing driver parameters isn't like playing checkers, it's like playing 3 dimensional chess. [/quote] what a quote!

[quote name='funkle' timestamp='1405976609' post='2507229'] Phil, thanks for your considered response. Think we can end the thread derail here! [/quote] But the thing that I was wondering...... nah Funkle's right - lets hear more about this 1x12

[quote name='CHRISDABASS' timestamp='1405973202' post='2507160'] Hi everyone! The plan for this has changed slightly.... It's not just the bass that is going on tour! It's us!! The two of us will be planning a trip (in a camper van) around the UK visting jam nights. gigs, guitar shops, even visiting you personally if you like!! This way you get to try more instruments and chat with us personally whilst having a brew or a beer! The dates and destinations still need to be worked out but we're really looking forward to it!! See you all soon! Cheers Chris [/quote] living near I need to come visit you when you're about! Got strings in at the moment? For everyone else - Alpher strings.... really really nice - fairly low tension round core, just a nice balanced tone - and having had them sat on my bass for ages they last too Replaced my previous faves of DR Fatbeams.

funkle - I'm not sure what you're asking- can you make up for speaker inefficiency with higher Xmax and more power? ..... you used ACME for years - surely you'll have an idea more than most!

[quote name='Phil Starr' timestamp='1405951839' post='2506847'] And I was worried about going off topic! [/quote] sorry! Though I do find the discussion interesting - it's good to understand the hows and whys of how things work. Also makes it easier to understand bass gear and the cab you're designing in relation to other gear (PA world mainly where they publish data) and other bass cabs.

Dear Non-Seller. Look at the shiytstorm of bad will you've stired up on here. Next time, or such a specialised item like a 7 string bass- just pay your basschat subs and advertise it on here! cheers LukeFRC

[quote name='Bobthedog' timestamp='1405894333' post='2506326'] Can a powerful amp play well quietly and, perhaps a stupid question, would any damage come to the valves through not having the thing turned up? [/quote] yes. that's what the volume control is for. and no, you're not going to damage it.

Which, aside from the church related issue is fascinating when it comes to looking at bass amplification- and probably why I wasn't feeling too short changed in my bottom end playing through a HK dart wedge with a -3db point at about 80Hz ... Slightly OT but for me is an eye opener in terms of the compromises in speaker design

So this weekend's observation - and I don't know where else to put it so I'll stick it here... Played bass at a wedding service this sunday, keys/vox/guitar/bass set up. Well the church we played at has quite a substantial (abet not the newest) PA system set up in it, including big subs.... and quite sensibly in the situation where you get lots of different bass players of different exp used a preamp straight into the desk and then a monitor for the bass player. Worked quite well - nice bass sound. Anyway, as I'm setting down I notice the preamp has a switch on giving me a 12dB high pass filter at 80Hz. And it sounded ok! It made me think about how our rig can/ or can't produce the low end.... and the effect it has.

Following on from a thread earlier this year about using PA gear as a bass rig I'm kinda wanting to pick up a pair of decent active speakers.... Secondhand is nice but where would i go to find that sorta stuff secondhand? PA land seemd to be another world compared to bass land!

I had a '57 - great basses - dig and the maple neck makes it all get a bit grindy great fun

If you're quick there are ways you can often still see the post even after it's been pulled.....

[quote name='Prime_BASS' timestamp='1405664076' post='2504075'] Our guitars brought a new combo the other week, I swear it weighs more than all my gear put together. [/quote] we used to lug this mental heavy 2x12 Fender Deville combo - two man lift most the time. Played a gig with a bigger band and helped them unload - it was funny how their Fender blues jr. sounded pretty much the same by the time you had mic'ed it and put it via the PA!
